From 1 June, Great Britain will bring zero-emission goods vans between 3.5 and 4.25 tonnes into the Class 7 MOT system and out of the heavier roadworthiness and tachograph regime that has applied because of their weight. The change is technical, but the effect is practical: electric vans that do the same jobs as diesel vans should now face rules that better match how they are actually used. (commonsbusiness.parliament.uk) For climate policy, that matters. The House of Lords Secondary Legislation Scrutiny Committee said the aim is to put these vehicles on the same footing as petrol and diesel equivalents, support uptake of zero-emission vans and help transport decarbonisation. This is not a flashy subsidy announcement; it is a piece of rule-fixing that could make cleaner freight a little easier to run. (publications.parliament.uk)

The rule change exists because batteries add weight. The Lords committee noted that 3.5 to 4.25 tonne zero-emission vans usually have the same appearance, function and load capacity as 3.5 tonne or lighter petrol and diesel vans, but have been caught by heavier regulatory treatment because the powertrain pushes them above the old threshold. Government consultation papers also show this segment is growing, from 188 registered vehicles at the end of 2021 to 2,233 by September 2024. (publications.parliament.uk) Zemo Partnership adds an important operational detail: battery-electric vans are best suited to city, suburban and back-to-base work, yet battery weight can trim payload by around 5 to 15 per cent for a small panel van and by up to 35 per cent for a large one. That helps explain why a 4.25 tonne allowance, and rules that recognise it, matter for delivery fleets trying to cut urban air pollution and freight emissions without giving up useful carrying capacity.

On testing, the switch is clear. These vans will be tested under Class 7 MOT rules, with the first test due three years after first registration and then annually, instead of staying in the heavy vehicle testing system from year one. The Explanatory Memorandum says the minimum tyre tread depth for passing will be 1.6mm, and the Lords committee noted that this is stricter than the 1.0mm requirement that previously applied. (commonsbusiness.parliament.uk) Consultation responses suggest operators wanted this reset. In the Department for Transport’s response, 63 per cent of respondents said heavy vehicle testing was more burdensome than MOT testing for equivalent 3.5 tonne vans, and 84 per cent said moving these zero-emission vans into Class 7 MOT testing would reduce burdens on operators. The department also said the administrative gain is likely to be felt especially strongly by mixed fleets running diesel and electric vans side by side. (gov.uk)

The other big shift is on drivers’ hours. Zero-emission goods vans over 3.5 tonnes and up to 4.25 tonnes will move out of the assimilated drivers’ hours and tachograph rules and into GB domestic drivers’ hours rules, with no distance cap attached to the exemption. Under the domestic regime, drivers are limited to 10 hours’ driving a day and 11 hours’ duty time, but there is no tachograph requirement and no specific record-keeping duty of the kind operators have faced under the assimilated rules. (commonsbusiness.parliament.uk) That simplification won support, but not without argument. In the government consultation, 67 per cent backed removing these vans from the assimilated rules, while opponents warned about fatigue risk in hard-worked parcel fleets and weaker enforcement without tachographs. The Lords committee also flagged a separate concern: once the Retained EU Law Act powers expire after June 2026, ministers will lack secondary legislation powers to amend the remaining assimilated drivers’ hours rules unless Parliament creates a new route.

This sits inside a bigger transport problem. Department for Transport statistics show domestic transport was still the UK’s largest emitting sector in 2023, responsible for 111.8 MtCO2e and 29 per cent of all greenhouse gas emissions; HGVs alone accounted for 18.2 MtCO2e. The Climate Change Committee’s Seventh Carbon Budget says 95 per cent of surface transport emissions in 2023 came from cars, HGVs and vans, with HGVs at 19 per cent and vans at 18 per cent. (gov.uk) The policy direction has already been moving towards zero-emission freight. Government documents say the ZEV mandate requires 10 per cent of new vans sold in Great Britain to be zero emission in 2024, rising to 70 per cent by 2030 and 100 per cent by 2035. Set against that timetable, aligning rules for 3.5 to 4.25 tonne electric vans looks less like a small tidy-up and more like basic maintenance for the clean transport plan. (gov.uk)

For operators, the practical takeaway is straightforward. Fleets using heavier electric vans should review MOT booking cycles, update compliance handbooks to reflect the move into GB domestic drivers’ hours rules, and brief drivers who travel to Northern Ireland, where the Lords committee warned tachograph requirements may still bite. That is an inference from the new rules and the committee’s warning, but it is the sort of housekeeping that prevents a policy gain turning into a compliance headache. (publications.parliament.uk) The commercial case is being helped by other measures, though cost and charging still matter. The Department for Transport extended the Plug-in Van Grant in February 2025, keeping support of up to £5,000 for larger zero-emission vans up to 4.25 tonnes and noting that the scheme has helped sell more than 80,000 electric and zero-emission vans. At the same time, government strategy papers say about 98 per cent of motorway service areas in England now have open-access chargepoints, while Zemo Partnership notes that battery-electric vans work best when fleets can charge back at base. (gov.uk)

No single regulation will solve clean freight. Upfront vehicle prices, depot connections and charging reliability still shape the real pace of change. But this measure removes a rules penalty that came from battery weight rather than from how these vans operate on the road, which is exactly the kind of practical policy repair that can help zero-emission logistics move beyond pilots and into normal fleet planning. (publications.parliament.uk) There is also a check built in. The regulations require government to review the new framework at least once every five years, and ministers have already said post-implementation review will look at road safety outcomes, including collision rates after the switch to Class 7 MOT testing. It is a useful example of what credible climate policy looks like: lighter admin where it helps, tighter evidence where it is needed, and a clearer route for cleaner vans doing everyday work.
